New information tips Chinese smartphone makers, Xiaomi, to adopt a 1/1.5-inch 50 MP camera that will displace the 64 MP Sony IMX686 as its CMOS sensor of choice. This move ensures that better camera performance will trickle down to the company's cheaper smartphones.

Finally using larger sensors instead of a gorillion of "pixels" that just end up requiring processing power to be binned together for a similar 4K image/scrambled with AI to simulate actual independent pixels
1/1.5" should be close to ≈50mm² (For people who care about actual sensor size). A step up from the ≈38mm² sensor in the Mi 11 Lite 5G, but still around half the area of the Mi 11 Ultra's main sensor (≈100mm², 1/1.2")
denoise algoritm way important than pixel size and pixel count. see comp between mi ultra vs iqoo phobe. same chip but massive difference.
